Decreased Productivity by andryou v0.46.56.13
Decreased Productivity (DP) creates a more "consistent" browsing experience (for you and others around you) by letting you control what you want to see ("stealth browsing" => text/page background colours, the cloaking of images, hiding page favicons, changing fonts, etc.). You can choose what style you want (e.g. green text on a black background) by going to the Options page (right-click on icon in address bar and click on "Options"). DP has tab-specific support and domain whitelisting/blacklisting!
Supports Arabic, German, English (US and British), Spanish, Tagalog, French, Italian, Japanese, Korean, Portuguese (Brazilian and Portugal), Russian, Vietnamese, Chinese (Simplified and Traditional)!
